How Much Is 8.7 Ounces of All-Purpose Flour in Cups?
Converting 8.7 ounces of all-purpose flour to cups gives 1.97 cups. First convert to grams (8.7 oz = 246.64g), then divide by the density of all-purpose flour (125.16g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 8.7 ounces of all-purpose flour
- Convert ounces to grams: 8.7 × 28.35 = 246.64g
- 1 cup of all-purpose flour = 125.16g
- 246.64g ÷ 125.16g/cup = 1.97 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Different flour types have very different weights per cup. Always check the specific flour your recipe calls for rather than using a generic "flour" conversion.

Understanding the Units
What is an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
